If he was thinking of you and doing the respectful thing, he would have gone fishing then *maybe* afterwards buy the crew a round or two of drinks and that's it. He then could have told the guys he had to go and maybe say he hasn't seen his wife in 2 weeks. SOB's right, guys don't usually care if you stay out at the bar with them... unless you are the one buying the drinks.
Maybe it's the alcohol talking? Once some people get started drinking they just can't stop and time gets away from you when you are inebriated. I'm guessing they started drinking while fishing?
I hope that you can make him understand that respect is just as important (if not more important) as love in a marriage. He really doesn't understand what he has with you Ali. I would not stay out late if I knew you were waiting at home for me. I would also be shouting from the rooftops about blessed I am to have this wonderful woman in my life.
Try not to blow up on him, but for sure let him know that it hurt you that he stayed out late with the guys. You miss him when he is gone for so long and you want to know that you are the most important person in his life... Numero Uno!
